Description

【０００１】
【発明の属する技術分野】
本発明は、複数の糸巻き付け面形成体により形成された環状の糸巻き付け面と緯糸係止体との係脱作用によって緯糸の測長貯留及び前記糸巻き付け面からの緯糸引き出しを制御し、前記糸巻き付け面の半径方向へ位置変位可能に前記複数の糸巻き付け面形成体を環状に配列した緯糸測長貯留装置の測長量調整に関するものである。
【０００２】
【従来の技術】
実開平３−１１１５８５号公報、特開２０００−７３２５５号公報に開示される巻き付け方式の緯糸測長貯留装置では、緯糸を巻き付けるためのドラムが複数のドラム片によって構成されている。これらのドラム片は、測長量と貯留量、又は貯留量のみ（以下、測長貯留量という）を変更可能にするために径方向に移動可能になっている。実開平３−１１１５８５号公報における複数のドラム片は、リンク機構を用いて径方向に同時に位置変位可能である。特開２０００−７３２５５号公報における複数のドラム片は、カム機構を用いて径方向に同時に位置変位可能である。
【０００３】
ドラム片を保持するためのドラムホルダは、ドラムの周囲で周回される糸ガイドを駆動するための回転軸に軸受けを介して相対回転可能に支持されている。ドラムホルダは、磁力を用いて回転軸の回転に関係なく静止保持される。
【０００４】
【発明が解決しようとする課題】
ドラムホルダ側を回転軸の回転に追随しないように静止保持することは、測長精度を高める上で重要である。ドラム片を径方向に移動して測長貯留量を調整するための測長貯留量調整機構は、ドラムホルダ側にある。測長貯留量調整機構の重量は、ドラム片及びドラムホルダの重量と共に軸受けを介して回転軸で受け止められる。ドラムホルダ側の重量が大きいほど、ドラムホルダ側を回転軸の回転に追随させないようにするための磁力を強くする必要がある。そのため、測長貯留量調整機構の存在は、磁力の強化を要求する。磁力の強化は、かなりのコストアップをもたらす。
【０００５】
本発明は、コストに関して有利な測長貯留量調整装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
そのために本発明は、静止保持される複数の糸巻き付け面形成体により形成された環状の糸巻き付け面と緯糸係止体との係脱作用によって緯糸の測長貯留及び前記糸巻き付け面からの緯糸引き出しを制御し、前記糸巻き付け面の半径方向へ位置変位可能に前記複数の糸巻き付け面形成体を環状に配列した緯糸測長貯留装置の測長貯留量調整装置を対象とし、請求項１の発明では、前記複数の糸巻き付け面形成体を支持する支持基板に対して着脱される円板形状の基枠と、前記基枠に取り付け位置変更可能に取り付けられる指示体と、前記指示体を前記基枠に取り付け位置変更可能に取り付けるための取り付け手段とを備えた測長貯留量調整装置を構成し、前記支持基板は、磁石の吸引力により静止保持されるとともに、前記複数の糸巻き付け面形成体が固定される前面と、前記前面より前方に突設される筒部とを備え、前記筒部に前記基枠の背面に形成された円形の凹部を嵌合した状態では、前記糸巻き付け面形成体が前記指示体に当接して前記糸巻き付け面の拡径方向又は縮径方向への移動を規制されると共に、前記糸巻き付け面形成体と前記指示体との当接によって前記支持基板に対する前記糸巻き付け面形成体の被支持位置を規定するようにした。
【０００７】
測長貯留量調整装置は、緯糸測長貯留装置の支持基板の筒部に対して着脱できる。従って、複数台の織機に用いられている複数の緯糸測長貯留装置における測長貯留量調整を１個の測長貯留量調整装置で遂行することができる。緯糸測長貯留装置の使用時には測長貯留量調整装置の重量が糸巻き付け面側に加わることはない。従って、測長貯留量調整機構が緯糸測長貯留装置に常時装着されている従来装置に比べ、糸巻き付け面側を回転軸の回転に追随させないようにするための磁力は弱くて済む。また、支持基板の筒部に基枠を嵌合する構成は、緯糸測長貯留装置に測長貯留量調整装置を装着する上で簡便である。
【０００８】
請求項２の発明では、請求項１において、前記糸巻き付け面形成体は、前記糸巻き付け面形成体の糸巻き付け面を形成する糸係合面と前記指示体との当接によって前記糸巻き付け面の拡径方向への移動を規制されるようにした。
【０００９】
糸巻き付け面を形成する糸係合面を基準にして測長貯留量の調整が行われるため、高い調整精度が得られる。
【００１１】
請求項３の発明では、請求項１及び請求項２のいずれか１項において、前記取り付け手段は、前記凹部の半径方向にのみ位置変更可能に前記基枠に前記指示体を嵌合する嵌合手段と、前記凹部の半径方向へ位置変更可能に前記基枠に前記指示体を撥ね込んだ状態で締め付け固定するねじ止め手段とから構成した。
【００１２】
基枠の凹部の径中心部を筒部の凸部の径中心部に合致させれば、指示体は糸巻き付け面の径方向にのみ位置変更可能となる。ねじ止め手段は、基枠に指示体を止着する上で簡便な手段である。
【００１３】
【発明の実施の形態】
以下、本発明を具体化した第１の実施の形態を図１〜図４に基づいて説明する。
【００１４】
図１に示す１１は駆動源となるモータであり、モータ１１の作動により回転軸１２が回転する。モータ１１は図示しない支持ブラケット上に支持されている。回転軸１２には糸巻き付け管１３が斜交して接続されている。回転軸１２内には基端から中間部にかけて糸通路１２１が形成されており、糸巻き付け管１３内の糸通路１３１が糸通路１２１に接続している。モータ１１の前面には非磁性体製のカバー１４が止着されており、回転軸１２の先端部には非磁性体製の円環状の支持基板１５がベアリング１６を介して相対回転可能に支持されている。支持基板１５の前面には円筒形状（即ち、円周面体形状）の筒部１５１が突設されている。筒部１５１と回転軸１２との間にはベアリング２０が介在されている。
【００１５】
カバー１４と支持基板１５との対向面には磁石１７，１８が対向して止着されている。磁石１７，１８は互いに吸引し合い、この吸引力によって支持基板１５がカバー１４に対して静止保持される。回転軸１２に止着された糸巻き付け管１３はカバー１４と支持基板１５との間を周回する。
【００１６】
図２に示すように、支持基板１５の前面には複数の糸巻き付け面形成体１９がねじ２１によって締め付け固定されている。糸巻き付け面形成体１９は、基部１９１と、測長部１９２とからなる。複数の測長部１９２の表面は、糸巻き付け面の一部となる凸弧面としての円弧面形状の糸係合面１９３となっている。糸係合面１９３は、略円形状の糸巻き付け面を形成する。糸巻き付け管１３は支持基板１５の周囲を周回し、糸通路１２１，１３１を通された緯糸Ｙが糸巻き付け面に巻き付けられる。支持基板１５は、複数の糸巻き付け面形成体１９を支持する支持部となる。筒部１５１は、前記支持部に設けられた円周面体形状の凸部となる。
【００１７】
基部１９１には長孔１９４が形成されている。ねじ２１は、長孔１９４を通って支持基板１５に螺合されている。長孔１９４は、糸巻き付け面形成体１９を支持基板１５の半径方向、即ち糸巻き付け面の半径方向への取り付け位置の変更を可能にする。
【００１８】
１つの糸巻き付け面形成体１９の近傍には電磁ソレノイド２２が配設されており、緯糸係止体２２１が電磁ソレノイド２２の励消磁により駆動される。緯糸係止体２２１は糸巻き付け面形成体１９上の孔１９５に出入りし、糸巻き付け管１３から繰り出される緯糸Ｙが緯糸係止体２２１の係止作用によって糸巻き付け面上に巻き付け貯留される。緯糸係止体２２１が孔１９５から離脱すれば糸巻き付け面上の巻き付け糸の引き出しが可能となる。電磁ソレノイド２２は、孔１９５を備えた糸巻き付け面形成体１９の半径方向への位置変更に応じて同じだけ半径方向へ位置変更できるようになっている。
【００１９】
図３（ａ），（ｂ）は、測長貯留量調整装置２６を示し、図４は測長貯留量調整装置２６の分解斜視図である。測長貯留量調整装置２６は、支持基板１５の筒部１５１に嵌合される円板形状の基枠２３と、基枠２３に取り付け位置変更可能に取り付けられる指示体２４と、基枠２３に指示体２４を締め付け固定するねじ２５とからなる。
【００２０】
図３（ｂ）に示すように、基枠２３の背面には円形の凹部２３１が形成されている。凹部２３１の径と筒部１５１の外径とは略同一であり、支持基板１５の筒部１５１は、凹部２３１に嵌合する。筒部１５１と凹部２３１とが嵌合した状態では、凹部２３１の径中心は、筒部１５１の径中心、即ち回転軸１２の回転中心軸線Ｌ（図１に図示）に一致する。図４に示すように、基枠２３の前面には支持溝２３２が凹部２３１の半径方向に延びるように形成されている。凹部２３１の径中心は、支持溝２３２の幅の中心にある。
【００２１】
合成樹脂製の指示体２４は、支持溝２３２に嵌めこまれている。指示体２４を支持溝２３２に嵌め込んだ状態では、指示体２４の前面と基枠２３の前面とは、面一となる。指示体２４の幅は、支持溝２３２の幅と同程度、かつ支持溝２３２に沿ってスライド可能に設定されている。支持溝２３２は、凹部２３１の半径方向にのみ位置変更可能に基枠２３に指示体２４を嵌め込む嵌め込み手段となる。指示体２４には指示印Ｔが刻設されており、基枠２３の前面には目盛りＭが刻設されている。
【００２２】
指示体２４の先端部には位置規制片２４１が直角に折曲した状態に形成されている。位置規制片２４１の裏面は、円弧面形状の規制面２４２となっている。凹弧面である規制面２４２の円弧面の円弧半径は、測長部１９２の糸係合面１９３の円弧面の円弧半径と同じにしてある。従って、規制面２４２と糸係合面１９３とは面接触可能である。
【００２３】
指示体２４には一対の長孔２４３，２４４が直列状態に形成されている。ねじ２５は、長孔２４４を通って基枠２３に螺合されている。ねじ２５を締め付けると、ねじ２５の頭部２５１が指示体２４に当接し、指示体２４が基枠２３に固定される。ねじ２５は、凹部２３１の半径方向へ位置変更可能に基枠２３に指示体２４を嵌め込んだ状態で締め付け固定するねじ止め手段となる。支持溝２３２及びねじ２５は、指示体２４を基枠２３に取り付け位置変更可能に取り付けるための取り付け手段を構成する。
【００２４】
図２に鎖線で示すように筒部１５１に基枠２３を嵌合した状態では、回転軸１２の軸線Ｌの方向に見た場合にねじ２１が長孔２４３を通して見える。長孔２４３，２４４は同形同大であり、長孔２４３，２４４の間隔は、基枠２３の半径方向にねじ２５の位置からねじ２１の位置への方向の距離に等しくなるようにしてある。
【００２５】
測長貯留量の調整は以下のように行われる。ねじ２５を緩めた状態で所望の織布の織幅に応じた目盛りＭの位置に指示印Ｔを合わせるように基枠２３に対して指示体２４を位置決めした後、ねじ２５を締めて基枠２３に指示体２４を固定する。次に、複数の糸巻き付け面形成体１９のうちの１つを締め付けているねじ２１を緩めて糸巻き付け面形成体１９を支持基板１５の径中心に近づけておき、筒部１５１に基枠２３を嵌合する。そして、測長部１９２が位置規制片２４１に当接するまで糸巻き付け面形成体１９を半径方向に移動する。測長部１９２の糸係合面１９３を位置規制片２４１の規制面２４２に面接触させた後、ねじ２１を締めつけて支持基板１５に糸巻き付け面形成体１９を固定する。他の糸巻き付け面形成体１９に対しても、それらのねじ２１を緩めた後に同様の操作を行えばよい。
【００２６】
第１の実施の形態では以下の効果が得られる。
（１-1）支持基板１５を備えた緯糸測長貯留装置と同じ装置が複数の織機で用いられている場合、緯糸測長貯留装置の支持基板１５の筒部１５１に対して着脱できる測長貯留量調整装置２６は、他の複数台の織機に用いられている複数の緯糸測長貯留装置における測長貯留量調整にも使用できる。従って、緯糸測長貯留装置に測長貯留量調整機構を予め組み付けてある従来構成に比べ、緯糸測長貯留装置の支持基板１５に対して着脱できる測長貯留量調整装置２６は、織機１台当たりに関して非常に安価である。
【００２７】
（１-2）緯糸測長貯留装置の使用時、即ち測長貯留を行なっているときには測長貯留量調整装置２６は、支持基板１５から外されており、測長貯留量調整装置２６の重量が支持基板１５に加わることはない。従って、測長貯留量調整機構が緯糸測長貯留装置に常時装着されている従来装置に比べ、支持基板１５を回転軸１２の回転に追随させないようにするための磁石１７，１８の磁力は弱くて済む。即ち、磁石１７，１８は、従来よりも小型のもので済み、磁石のコストは低減する。
【００２８】
（１-3）糸巻き付け面形成体１９は、糸係合面１９３と指示体２４の規制面２４２との当接によって糸巻き付け面の拡径方向への移動を規制される。即ち、支持基板１５に対する糸巻き付け面形成体１９の被支持位置が糸係合面１９３と規制面２４２との当接によって規定される。糸巻き付け面を形成する糸係合面１９３を基準にして測長貯留量の調整が行われるため、高い調整精度が得られる。
【００２９】
（１-4）測長貯留量調整装置２６は、基枠２３と筒部１５１との凹凸の嵌合によって支持基板１５に取り付けられる。支持基板１５の筒部１５１に基枠２３を嵌合する構成は、緯糸測長貯留装置に測長貯留量調整装置２６を装着する上で簡便である。
【００３０】
（１-5）凹部２３１に筒部１５１を嵌合した状態では、凹部２３１の径中心と筒部１５１の径中心とが一致し、凹部２３１の径中心が支持溝２３２の幅中心にある。従って、支持溝２３２に嵌め込まれた指示体２４は、糸巻き付け面の径方向にのみ位置変更可能である。支持溝２３２に指示体２４を嵌め込む構成は、指示体２４を糸巻き付け面の径方向にのみ位置変更可能とする上で簡便である。
【００３１】
（１-6）ねじ止め手段を構成するねじ２５は、基枠２３に指示体２４を止着する上で簡便な手段である。
（１-7）支持溝２３２に嵌め込まれた指示体２４は、ねじ２５を中心とした基枠２３に対する回動を阻止される。支持溝２３２に指示体２４を嵌め込む構成は、指示体２４がねじ２５を中心にして回動しないようにする上で簡便な構成である。
【００３２】
（１-8）糸巻き付け面形成体１９がねじ２１を中心にして糸巻き付け面の周方向に傾くと、正確な測長貯留量が得られない。糸係合面１９３と規制面２４２とは面接触し、糸係合面１９３と規制面２４２とが面接触した状態では糸巻き付け面形成体１９がねじ２１を中心として回動することはない。即ち、糸係合面１９３と規制面２４２とを面接触させる構成は、糸巻き付け面形成体１９がねじ２１を中心にして糸巻き付け面の周方向に傾動しないようにする。
【００３３】
（１-9）糸巻き付け面形成体１９の糸係合面１９３に傷が付くと、糸巻き付け面から引き出し解舒される緯糸Ｙの引き出し抵抗が増し、緯入れ不良を発生するおそれが高くなる。糸係合面１９３に当接する指示体２４を合成樹脂製とした構成は、指示体２４と糸係合面１９３との当接による糸係合面１９３の損傷を回避する上で有効である。
【００３４】
（１-10)ねじ２１の締め付けは、糸巻き付け面形成体１９と指示体２４とを当接した状態で長孔２４３からねじ回しを通して行える。従って、糸係合面１９３と規制面２４２との面接触を保持しておけば、糸巻き付け面形成体１９は測長貯留量調整装置２６によって規定された支持基板１５に対する被支持位置で傾くことなく支持基板１５に固定される。
【００３５】
（１-11)指示体２４の前面と基枠２３の前面とが面一であるため、目盛りＭと指示印Ｔとは同一面上にある。目盛りＭと指示印Ｔとを同一面上に設ける構成は、正確な測長貯留量調整に有効である。
【００３６】
次に、図５〜図７の第２の実施の形態を説明する。第１の実施の形態と同じ構成部には同じ符号が付してある。
図５及び図６に示すように、測長貯留量調整装置２７は、円形状の基枠２８と、基枠２８の周縁のフランジ２８１に形成された複数の支持溝２８２にそれぞれ嵌め込まれた指示体２９と、フランジ２８１の内側の凹部２８３に嵌入されたカム体３０と、基枠２８の径中心を貫通してカム体３０の径中心に螺合されるねじ３１とからなる。
【００３７】
指示体２９の基端部にはピン２９１が取り付けられている。カム体３０には複数のカム溝３０１が形成されており、カム溝３０１にはピン２９１が嵌め込まれている。ねじ３１を緩めた状態でカム体３０をねじ３１を中心にして回動すると、指示体２９がピン２９１とカム溝３０１とのカム作用によって支持溝２８２に沿って基枠２８の半径方向へ移動する。
【００３８】
図７に示すように、支持基板１５の筒部１５１は、凹部２８３に嵌合する。筒部１５１と凹部２８３とを嵌合した状態では、指示体２９の先端部の位置規制片２９２が糸巻き付け面形成体１９の糸係合面１９３に面接触可能である。位置規制片２９２は、第１の実施の形態における位置規制片２４１と同じ形状である。
【００３９】
図６に示すように、目盛りＭ１は、指示体２９の側面に設けられている。支持溝２８２とフランジ２８１の外周面との成す角Ｔ１が指示印となる。指示体２９に設けられた長孔２９３は、第１の実施の形態における長孔２４３と同じ役割を果たす。
【００４０】
第２の実施の形態では、第１の実施の形態と同様の効果が得られる。又、支持基板１５に対する複数の糸巻き付け面形成体１９の被支持位置の設定が同時に行える。
【００４１】
次に、図８の第３の実施の形態を説明する。第１の実施の形態と同じ構成部には同じ符号が付してある。
指示体２４Ａの先端部の位置規制片２４１Ａの外周面２４５は、糸巻き付け面形成体１９の測長部１９２の内周面１９５に面接触する。第３の実施の形態の測長貯留量調整装置２６Ａは、第１の実施の形態における（１-1）項、（１-2）項、（１-4）〜（１-7）項と同じ効果をもたらす。
【００４２】
次に、図９の第４の実施の形態を説明する。第１の実施の形態と同じ構成部には同じ符号が付してある。
測長貯留量調整装置３２は、円筒形状の基枠３３と、基枠３３に一体形成されたアーム片３４と、アーム片３４の先端部の折曲部に形成された孔３４１に挿通された指示体３５と、アーム片３４に螺合されて指示体３５に当接するねじ３６とからなる。基枠３３には支持基板１５の筒部１５１が嵌合される。アーム片３４は、基枠３３の半径方向に延びている。アーム片３４に形成された孔３４２は、ねじ２１を締めつける際にねじ回しを通すためのものである。ねじ３６を緩めれば、指示体３５は、アーム片３４の長さ方向に移動可能である。
【００４３】
指示体３５の先端部の位置規制片３５１は、第１の実施の形態における位置規制片２４１と同じ形状をしている。位置規制片３５１は、糸巻き付け面形成体１９の糸係合面１９３に面接触する。
【００４４】
第４の実施の形態では、第１の実施の形態における（１-1）〜（１-3）項、（１-4）〜（１-7）項と同じ効果が得られる。
本発明では以下のような実施の形態も可能である。
【００４５】
（１）第１の実施の形態において、目盛りＭを指示体２４側に設け、指示印Ｔを基枠３３側に設けること。
（２）第１の実施の形態において、ラック−ピニオン機構を用いて指示体２４を基枠２３に対して半径方向へ移動できるようにすること。この場合、ラックは指示体２４側に設けられ、ピニオンは基枠２３側に設けられる。指示体２４は、ラック−ピニオン機構におけるセルフロック作用によって基枠２３に固定される。
【００４６】
（３）第２の実施の形態において、カム溝を有するカム体の代わりにリンク機構を用いて複数の指示体２９を同時に動かせるようにすること。

BACKGROUND OF THE INVENTION
The present invention controls the measurement and storage of the weft yarn and the weft drawing from the yarn winding surface by engaging and disengaging the annular yarn winding surface formed by a plurality of yarn winding surface forming bodies and the weft locking body, The present invention relates to a length measurement adjustment of a weft length measurement storage device in which the plurality of yarn winding surface forming bodies are arranged in an annular shape so as to be displaceable in the radial direction of the yarn winding surface.
[0002]
[Prior art]
In the winding type weft length measuring and storage device disclosed in Japanese Utility Model Laid-Open No. 3-111585 and Japanese Patent Laid-Open No. 2000-73255, a drum for winding a weft is composed of a plurality of drum pieces. These drum pieces are movable in the radial direction in order to make it possible to change the length measurement amount and the storage amount, or only the storage amount (hereinafter referred to as the length measurement storage amount). The plurality of drum pieces in Japanese Utility Model Laid-Open No. 3-111585 can be simultaneously displaced in the radial direction by using a link mechanism. The plurality of drum pieces in Japanese Patent Laid-Open No. 2000-73255 can be simultaneously displaced in the radial direction by using a cam mechanism.
[0003]
A drum holder for holding the drum piece is supported by a rotation shaft for driving a yarn guide that circulates around the drum through a bearing so as to be relatively rotatable. The drum holder is held stationary using magnetic force regardless of the rotation of the rotating shaft.
[0004]
[Problems to be solved by the invention]
Holding the drum holder side stationary so as not to follow the rotation of the rotating shaft is important for improving the length measurement accuracy. The length measurement storage amount adjustment mechanism for adjusting the length measurement storage amount by moving the drum piece in the radial direction is on the drum holder side. The weight of the length measuring and storing amount adjusting mechanism is received by the rotating shaft through the bearing together with the weight of the drum piece and the drum holder. The greater the weight on the drum holder side, the stronger the magnetic force that prevents the drum holder side from following the rotation of the rotating shaft. Therefore, the existence of the length measurement storage amount adjustment mechanism requires the strengthening of the magnetic force. The strengthening of magnetic force brings about a considerable cost increase.
[0005]
An object of the present invention is to provide a length measurement and storage amount adjustment device that is advantageous in terms of cost.
[0006]
[Means for Solving the Problems]
For this purpose, the present invention relates to the measurement and storage of the weft yarn and the weft yarn from the yarn winding surface by the engagement / disengagement of the annular yarn winding surface formed by a plurality of yarn winding surface forming bodies held stationary and the weft locking body. 2. The length measurement and storage amount adjustment device of a weft length measurement and storage device in which the plurality of yarn winding surface forming bodies are arranged in an annular shape so as to be capable of displacement in the radial direction of the yarn winding surface by controlling the drawing.

The motor 11 is supported on a support bracket (not shown). A thread winding tube 13 is obliquely connected to the rotary shaft 12. A thread passage 121 is formed in the rotary shaft 12 from the base end to the middle portion, and a thread passage 131 in the thread winding tube 13 is connected to the thread path 121. A non-magnetic cover 14 is secured to the front surface of the motor 11, and a non-magnetic annular support substrate 15 is supported at the tip of the rotary shaft 12 via a bearing 16 so as to be relatively rotatable. Has been. A cylindrical portion 151 (that is, a circumferential surface shape) is protruded from the front surface of the support substrate 15. A bearing 20 is interposed between the cylindrical portion 151 and the rotating shaft 12.
[0015]
Magnets 17 and 18 are fixed to face each other between the cover 14 and the support substrate 15. The magnets 17 and 18 attract each other, and the support substrate 15 is held stationary with respect to the cover 14 by this attraction force. The yarn winding tube 13 fixed to the rotating shaft 12 circulates between the cover 14 and the support substrate 15.
[0016]
As shown in FIG. 2, a plurality of yarn winding surface forming bodies 19 are fastened and fixed to the front surface of the support substrate 15 by screws 21. The yarn winding surface forming body 19 includes a base portion 191 and a length measuring portion 192. The surface of the plurality of length measuring portions 192 is an arcuate surface-shaped thread engaging surface 193 as a convex arc surface that is a part of the thread winding surface. The thread engaging surface 193 forms a substantially circular thread winding surface. The yarn winding tube 13 circulates around the support substrate 15, and the weft Y passed through the yarn passages 121 and 131 is wound around the yarn winding surface. The support substrate 15 serves as a support portion that supports the plurality of yarn winding surface forming bodies 19. The cylindrical part 151 is a convex part having a shape of a circumferential face provided in the support part.
[0017]
A long hole 194 is formed in the base 191. The screw 21 is screwed to the support substrate 15 through the long hole 194. The long hole 194 allows the attachment position of the yarn winding surface forming body 19 to be changed in the radial direction of the support substrate 15, that is, in the radial direction of the yarn winding surface.

If the weft locking member 221 is detached from the hole 195, the winding thread on the thread winding surface can be pulled out. The electromagnetic solenoid 22 can be changed in position in the radial direction by the same amount in accordance with the change in position in the radial direction of the yarn winding surface forming body 19 provided with the hole 195.
[0019]
3A and 3B show the length measurement storage amount adjusting device 26, and FIG. 4 is an exploded perspective view of the length measurement storage amount adjusting device 26. FIG. The length measurement and storage amount adjusting device 26 includes a disk-shaped base frame 23 fitted to the cylindrical portion 151 of the support substrate 15, an indicator 24 attached to the base frame 23 so that the attachment position can be changed, and a base frame 23. It comprises a screw 25 for fastening and fixing the indicator 24.
[0020]
As shown in FIG. 3B, a circular recess 231 is formed on the back surface of the base frame 23. The diameter of the concave portion 231 and the outer diameter of the cylindrical portion 151 are substantially the same, and the cylindrical portion 151 of the support substrate 15 is fitted into the concave portion 231. In a state where the cylindrical portion 151 and the concave portion 231 are fitted, the radial center of the concave portion 231 coincides with the radial center of the cylindrical portion 151, that is, the rotation center axis L (shown in FIG. 1) of the rotary shaft 12. As shown in FIG. 4, a support groove 232 is formed on the front surface of the base frame 23 so as to extend in the radial direction of the recess 231. The center of the diameter of the recess 231 is at the center of the width of the support groove 232.
[0021]
The synthetic resin indicator 24 is fitted in the support groove 232. In a state where the indicator 24 is fitted in the support groove 232, the front surface of the indicator 24 and the front surface of the base frame 23 are flush with each other. The width of the indicator 24 is set to be approximately the same as the width of the support groove 232 and is slidable along the support groove 232. The support groove 232 serves as a fitting means for fitting the indicator 24 into the base frame 23 so that the position can be changed only in the radial direction of the recess 231. An indication mark T is engraved on the indicator 24, and a scale M is engraved on the front surface of the base frame 23.
[0022]
A position restricting piece 241 is formed at a right angle at the tip of the indicator 24. The back surface of the position restricting piece 241 is a restricting surface 242 having an arcuate surface shape. The arc radius of the arc surface of the regulating surface 242 that is a concave arc surface is the same as the arc radius of the arc surface of the yarn engaging surface 193 of the length measuring portion 192. Therefore, the regulating surface 242 and the thread engaging surface 193 can be brought into surface contact.
[0023]
The indicator 24 has a pair of long holes 243 and 244 formed in series. The screw 25 is screwed into the base frame 23 through the long hole 244. When the screw 25 is tightened, the head 251 of the screw 25 comes into contact with the indicator 24 and the indicator 24 is fixed to the base frame 23. The screw 25 serves as a screwing means for tightening and fixing the indicator 24 in the base frame 23 so that the position of the screw 231 can be changed in the radial direction. The support groove 232 and the screw 25 constitute an attachment means for attaching the indicator 24 to the base frame 23 so that the attachment position can be changed.
[0024]
In a state where the base frame 23 is fitted to the cylindrical portion 151 as indicated by a chain line in FIG. 2, the screw 21 can be seen through the long hole 243 when viewed in the direction of the axis L of the rotary shaft 12. The long holes 243 and 244 have the same shape and the same size, and the distance between the long holes 243 and 244 is set to be equal to the distance in the radial direction of the base frame 23 from the position of the screw 25 to the position of the screw 21. .
[0025]
Adjustment of the measured storage volume is performed as follows. After the screw 25 is loosened, the indicator 24 is positioned with respect to the base frame 23 so that the indicator mark T is aligned with the position of the scale M corresponding to the desired woven width of the woven fabric, and then the screw 25 is tightened to tighten the base frame. The indicator 24 is fixed to 23. Next, the screw 21 tightening one of the plurality of thread winding surface forming bodies 19 is loosened to keep the thread winding surface forming body 19 close to the center of the diameter of the support substrate 15, and the base portion 23 is placed on the cylindrical portion 151. Mating. The thread winding surface forming body 19 is moved in the radial direction until the length measuring unit 192 contacts the position restricting piece 241. After the thread engaging surface 193 of the length measuring section 192 is brought into surface contact with the regulating surface 242 of the position regulating piece 241, the screw 21 is tightened to fix the yarn winding surface forming body 19 to the support substrate 15. The same operation may be performed on the other thread winding surface forming bodies 19 after the screws 21 are loosened.
[0026]
The following effects can be obtained in the first embodiment.
(1-1) When the same device as the weft length measuring and storing device provided with the support substrate 15 is used in a plurality of looms, the length measuring that can be attached to and detached from the cylindrical portion 151 of the support substrate 15 of the weft length measuring and storing device. The storage amount adjustment device 26 can also be used for length measurement storage amount adjustment in a plurality of weft length measurement storage devices used in a plurality of other looms. Therefore, compared to the conventional configuration in which the length measurement storage amount adjustment mechanism is pre-assembled in the weft length measurement storage device, the length measurement storage amount adjustment device 26 that can be attached to and detached from the support substrate 15 of the weft length measurement storage device is one loom. It is very cheap with respect to winning.
[0027]
(1-2) When the weft length measuring and storing device is used, that is, when measuring and storing, the length measuring and storing amount adjusting device 26 is removed from the support substrate 15, and the weight of the length measuring and storing amount adjusting device 26 is Is not added to the support substrate 15. Therefore, the magnetic force of the magnets 17 and 18 for preventing the support substrate 15 from following the rotation of the rotary shaft 12 is weaker than that of the conventional device in which the length measurement storage amount adjusting mechanism is always mounted on the weft length measurement storage device. I'll do it. That is, the magnets 17 and 18 are smaller than the conventional one, and the cost of the magnet is reduced.
[0028]
(1-3) The yarn winding surface forming body 19 is restricted from moving in the diameter increasing direction of the yarn winding surface by contact between the yarn engaging surface 193 and the regulating surface 242 of the indicator 24. That is, the supported position of the yarn winding surface forming body 19 with respect to the support substrate 15 is defined by the contact between the yarn engaging surface 193 and the regulating surface 242. Since the length measurement storage amount is adjusted based on the yarn engagement surface 193 that forms the yarn winding surface, high adjustment accuracy is obtained.
[0029]
(1-4) The length measurement storage amount adjusting device 26 is attached to the support substrate 15 by fitting the unevenness between the base frame 23 and the cylindrical portion 151. The configuration in which the base frame 23 is fitted to the cylindrical portion 151 of the support substrate 15 is simple in mounting the length measurement storage amount adjusting device 26 to the weft length measurement storage device.
[0030]
(1-5) In a state where the cylindrical portion 151 is fitted in the concave portion 231, the radial center of the concave portion 231 coincides with the radial center of the cylindrical portion 151, and the radial center of the concave portion 231 is at the width center of the support groove 232. Therefore, the position of the indicator 24 fitted in the support groove 232 can be changed only in the radial direction of the yarn winding surface. The configuration in which the indicator 24 is fitted into the support groove 232 is simple in that the position of the indicator 24 can be changed only in the radial direction of the yarn winding surface.
[0031]
(1-6) The screw 25 constituting the screwing means is a simple means for fixing the indicator 24 to the base frame 23.
(1-7) The indicator 24 fitted in the support groove 232 is prevented from rotating with respect to the base frame 23 around the screw 25. The configuration in which the indicator 24 is fitted into the support groove 232 is a simple configuration in order to prevent the indicator 24 from rotating about the screw 25.
[0032]
(1-8) If the thread winding surface forming body 19 is inclined in the circumferential direction of the thread winding surface with the screw 21 as the center, an accurate length measurement storage amount cannot be obtained. The yarn engaging surface 193 and the regulating surface 242 are in surface contact, and the yarn winding surface forming body 19 does not rotate around the screw 21 in a state where the yarn engaging surface 193 and the regulating surface 242 are in surface contact. That is, the configuration in which the yarn engaging surface 193 and the regulating surface 242 are in surface contact prevents the yarn winding surface forming body 19 from tilting in the circumferential direction of the yarn winding surface with the screw 21 as the center.
[0033]
(1-9) If the yarn engaging surface 193 of the yarn winding surface forming body 19 is damaged, the pulling resistance of the weft Y pulled out and unwound from the yarn winding surface increases, and the possibility of poor weft insertion increases. . The configuration in which the indicator 24 that contacts the thread engaging surface 193 is made of synthetic resin is effective in avoiding damage to the thread engaging surface 193 due to contact between the indicator 24 and the thread engaging surface 193.
[0034]
(1-10) The screw 21 can be tightened through the long hole 243 through a screwdriver while the yarn winding surface forming body 19 and the indicator 24 are in contact with each other. Therefore, if the surface contact between the yarn engaging surface 193 and the regulating surface 242 is maintained, the yarn winding surface forming body 19 is inclined at the supported position with respect to the support substrate 15 defined by the length measurement storage amount adjusting device 26. Without being fixed to the support substrate 15.
[0035]
(1-11) Since the front surface of the indicator 24 and the front surface of the base frame 23 are flush with each other, the scale M and the indicator mark T are on the same plane. The configuration in which the scale M and the instruction mark T are provided on the same plane is effective for accurate measurement and storage amount adjustment.
